Definitions

  • the invention concerns a process for the perforation of individual pieces of sheet material including leather, artificial leather, foam, paper, filter paper, cardboard and foils by at least one spike group with perforation spikes where the pieces are guided into the working zone of the at least one spike group by an endless transport device and are pulled off from the perforating spikes by at least one hold-down device.
  • Perforation processes are used to make sheet material permeable to either air or steam, i.e., to make them breathable, or for example to give a certain filtering characteristic to filter papers.
  • Main applications are automobile seat covers, parts of shoes, gloves, articles of clothing and filter paper.
  • the object of the invention is therefore to make available a perforating process by which non-endless and odd-shaped or irregular sheet material pieces can be provided with evenly distributed perforations of high perforation density per surface unit, without a resulting blockage of the perforating process.
  • the sheet material pieces are held to the conveyor device by a hold-down band which is moved along with the conveyor device and through which the perforating spikes can pass.
  • Such a process can be especially advantageously used for leather and cuts of leather since by its nature this material only occurs in finite sizes.
  • the process can be carried out in stationary manner, for example in a form of a stamping device, quasi-continuously and/or in step-wise cross transport, or continuously.
  • the hold-down band runs synchronously with the sheet material pieces through the working zone and/or the roller gap of the at least one spike roll.
  • Such a hold-down band of a limited length can be drawn off a supply roll, be guided in a stretched condition through the roller gap between the at least one spike roller and the pieces being transported by the conveyor device and then be rolled up on a take-up roll for repeated, and especially multiple, use.
  • the hold-down band is designed as an endless band and is passed multiple times at the transport speed through the working zone of the at least one spike roll, i.e., through the roller gap.
  • Material that can be used for such hold-down bands can be textile bands, especially woven bands, which exhibit a sufficient durability vis-a-vis the perforation spikes.
  • the invention also relates to a device for the perforation of sheet materials including leather, artificial leather, foam, paper, filter paper, cardboard and foils, having at least one transport device for the sheet material, at least one spike group with perforation spikes and at least one hold-down device arranged between the transport device and the spike group, which hold-down device pulls the individual sheet material pieces away from the perforating spikes.
  • such a device is designed according to the invention such that the hold-down device is designed as a hold-down band which can pass synchronously with the sheet material pieces through the roller gap between the at least one spike roller and the transport device.
  • Such a device is also suitable as a universal device for providing endless material with evenly and densely distributed perforation holes, while in contrast, devices according to the prior art are not suitable for perforating sheet material pieces which are of irregular or unequal shapes.
  • the invention makes it possible to easily achieve hole densities of up to 50 holes/cm 2 using only one spike roller with the appropriate number of spikes.
  • the at least one spike group is formed by one spike roller and if the hold-down band runs synchronously with the sheet material pieces through the roller gap between the at least-one spike roller and the sheet material pieces located on the transport device, especially if the hold-down band is designed as an endless band.
  • the effect of the hold-down band is especially advantageous if one guide roller each is arranged before the first and behind the last spike roller whereby the guide roller holds the hold-down band on the sheet material pieces.
  • the angle of belt contact of the spike rolls is kept as small as possible and the hold-down band is protected from excessive wear.
  • FIGS. 1 and 2 Two embodiments of the invention are described below in more detail by way of FIGS. 1 and 2. There are shown, in side views, in
  • FIG. 1 a device with a non-endless hold-down band
  • FIG. 2 a device analogous to FIG. 1, but with an endless hold-down band.
  • FIG. 1 shows a machine frame 1 on which is arranged a transport device 2 designed as an endless conveyor belt 3.
  • the latter is guided over two deflection rollers 4 and 5 and three support rollers 6, and is made of stretch-resistant material of which at least the outer surface is soft and composed of for example a foam material, fleece or felt.
  • Bearing brackets, drives and tensioning devices are not shown for the sake of simplicity.
  • One spike group each designed as a spike roller 7, is arranged axially parallel over the support rollers 6.
  • the number of the spike rollers is variable and depends on the desired density of perforations, which can be for example 150 holes/cm 2 behind the last spike roller 7.
  • a roller gap 8 is formed in each instance between the support rollers 6 andL the spike rollers 7 through which gap are passed the conveyor belt 3, the pieces 9 and the hold-down device designed as a hold-down band 10, in this order if viewed from below.
  • This hold-down band 10 comes from the supply roll 11 and is again rolled up on a take-up roll 12, both rolls being mounted on a support frame 13.
  • the hold-down band 10 and the deflection rollers 14 are kept under tension by a drive and a brake (both not shown).
  • the hold-down band 10 In front of the first, and behind the last, spike roller 7, the hold-down band 10 is held, stretched downward and horizontally, to the pieces 9 by guide rollers 15 and 16 whereby the spikes naturally penetrate the hold-down band as well.
  • the pieces 9 are placed on the conveyor on the left side, and when perforated, fall into a container 17.
  • FIG. 2 differs from FIG. 1 in that an endless hold-down band 10a is used which band is kept stretched by the horizontal displacement of the right deflection roller 14 by a tensioning device 18, indicated by a double arrow.
  • the relative thickness and length of the spikes as shown is exaggerated.
